I'm assuming that pills A and B taste differently. So take half of each, that way you will know which tastes different, and then u can half the other half from differently tasting pill. Thus you will have exact amount of dose.

我们可以将手中的三个药片均进行二等分，然后将其中一半放到左面，另一半放到右面。这样下来，左面和右面分别有半个A和一个B。接下来，我们再从A中拿出一片药，同样进行等分操作，即进行二等分，然后将其中一半放到左面，另一半放到右面。

这样左右两面都有一个A和一个B，吃其中一组，第二天吃剩下的一组即可。

We can divide the three pills in our hand into two parts, and then put half of them on the left side and the other half on the right side. In this way, there are half A and one B on the left and right respectively. Next, we take out a piece of pill from A, and perform the same division operation, that is, divide it into two equal parts, and then put half of it on the left side and the other half on the right side.

In this way, there is an A and a B on the left and right sides, eat one of them, and eat the rest the next day.
